MPDM Diaphragm Metering Pump Features:

1.        Seal without leakage, simple maintenance, eccentric scam as the driving end with compact structure and small install space.

2.        Maximum flow up to 600L/H, Maximum pressure up to 0.5Mpa, Metering accuracy: +/- 2%, Temp -30 to 50 degree, viscosity 0 to 800mm2/s.

3.        Oil lubrication, only needing to change oil regularly without maintaining the lubricating system, Long-lived diaphragm

4.        Flow can be adjusted whether the pump is on or not. Effective stoke of diaphragm can be adjusted to change pump flow within 1% to 100%

MPDM Diaphragm Metering Pump
Working Principles

The motor reduces speed through worm gear, pinning the cam and pushing crosshead to make diaphragm move reciprocally and change the volume chamber. And absorb and discharge liquid under the control of inlet and outlet valves.
 

MPDM Diaphragm Metering Pump Material

Alloy pump casing or stainless steel pump casing

PTFE diaphragm, which is anti-corrosion, durable and suitable for various corrosive and dangerous liquid

Many optional materials for the pump head(wet parts), like PTFE, PVC, SS304, SS316 and so on, for various combustible, explosive, poisoning, radioactive, strong corrosive liquid.

Application for the MPDM Metering Pump

Petroleum, chemo industry, water treatment, environment protection, paper making, pharmacy, printing and dyeing, metallurgy and mines.

Name meaning for MPDM Diaphragm Metering Pump:

For example MPDT-5/0.5

MP---Metering pump for name.

D---Diaphragm metering type pump (D for mechanical diaphragm metering pump type, P for piston/plunger metering pump type, H for hydraulic diaphragm metering pump)

T—Small base type(seat),(T for tiny, S for small, M for middle, B for big), the pump base/seat has a great relation with the pump performance. Usually the bigger pump base/seat has bigger capacity

5---pump capacity is 1.0 L/H, 0.5---Pump pressure is 0.5Mpa
